Patent ES-228236-A1 (ES)
Title: Organic phosphate, salts thereof, and process for the manufacture thereof
IPC: C07F9/58
Filed: 1956-04-28
Abstract: The invention comprises pyridyl-(3)-methyl dihydrogen phosphate and alkali metal, alkaline earth metal and ammonium salts thereof. The products may be obtained by phosphorylating pyridyl-(3)-methyl alcohol by treating it with a mixture of phosphorus pentoxide and phosphoric acid at an elevated temperature, hydrolysing any polyphosphates contained in the resulting mixture by heating same in acid solution, passing the hydrolysate through a cationic exchange resin and separating off that fraction of the eluate which contains the required pyridyl-(3)-methyl dihydrogen phosphate and, if desired, treating same with a precipitating agent or, where a salt is required, carrying out the defined process and treating said fraction or the pyridyl-(3)-methyl dihydrogen phosphate precipitated therefrom with an alkali metal hydroxide, alkaline earth metal hydroxide or ammonium hydroxide followed by isolation of the resulting salt by precipitation or concentration. The phosphorylation may suitably be conducted at 60 DEG C. and hydrochloric acid may conveniently be used in the hydrolysis step. Suitable cationic exchange resins are sulphonic acid resins in their acid form. Acetone may be used as the precipitating agent in either case. Before feeding the hydrolysate on to the column containing the cationic-exchange resin it is preferred to remove the bulk of inorganic oaterial contained therein by treating it with phenol and partitioning the phenolic layer between ether and water. The resulting aqueous layer contains the required product and is then fed on to the column. Examples are given for the production of the pyridyl-(3)-methyl dihydrogen phosphate and its mono- and disodium salts. The products are stated to be effective vasodilators.

Title: Grinding plants
IPC: C04B7/36
Filed: 1964-08-26
Abstract: A method of producing cement ready for packing into bags comprises grinding cement clinker in a mill, cooling the ground cement after it leaves the mill by carrying it in an upward current of air, separating it from the air when cooled and delivering at least some of the ground separated cement to a discharge conveyer. Ground cement from a mill 1, Fig. 1, is conveyed by means of a pipe 8 and warm conveyer 9 to a cooling riser pipe 11 the lower end of which is open to the atmosphere. The suspended cement particles are separated from the air in a cyclone 13 and passed through a pipe 27 to the feed tank of a discontinuous pneumatic conveyer 30. The air heated by the cement is conveyed by a fan 12 to a dust filter 16 the separated dust from which is caught by worm conveyer 18 and led into conveyer 9. Pipe 8 has an extension 20 through which pass water vapour and cement particles under vacuum produced by fan 21. The dust is separated in cyclone 22 and led to conveyer 9 while the air is conveyed to the filter 16. In a modification, the pipe 8 opens into the bottom of an elevator 32, Fig. 3, which raises the cement so that it flows down through a pneumatic conveying trough 33 into an air separator 34 in which it is divided into two fractions. The coarse fraction is conveyed via pneumatic trough 37 to the inlet end of the mill for further grinding. The fine fraction is conveyed via worm conveyer 41 to the pipe 11. Conveying air is sucked in through a pipe end 45. Dust from the top of elevator 32, from trough 33 and from trough 37 is passed through pipes 48, 49, 50 respectively which lead to a common pipe 47 connected to the filter 16. In another modification, Fig. 4 (not shown), two filters are provided and the common pipe is connected to the riser pipe instead of the filter. In a further modification, Fig. 5 (not shown), cement from the mill is fed to the riser pipe the upper end of which is connected to a cyclone from which air containing fine dust is conveyed by a fan to the filter while coarser cement is passed to an air separator where the cement is divided into two fractions, the finer fraction being carried by a worm conveyer to the feed tank of the pneumatic conveyer while the coarser fraction is returned to the inlet end of the mill for further grinding.

Title: Semiconductor device fabrication utilizing {21 100{22 {0 oriented substrate material
IPC: H01L21/8222
Filed: 1968-10-18
Abstract: A high conductivity N type zone in a device formed in a body of monocrystalline semiconductor material having a face parallel to a 100 crystallographic plane has a surface concentration of phosphorus of 2À5 to 4 x 103 parts per million by weight. This is achieved without significant precipitation of phosphorus due to the low dislocation density in thus aligned material. A junction isolated transistor (Fig. 2) in a typical solid circuit embodiment is formed on a 10-20 ohm. cm. P type silicon wafer 30 cut from a crystal grown along a 100 axis with its faces in a 100 plane. Subcollector region 32 is formed by diffusion and extends during epitaxial deposition of N-type epitaxial layer 34. A grid of isolation walls 37 is next diffused in prior to formation of base 38 and emitter 40 by successive diffusions. Alternatively region 32 is formed by ion implantation or etch and refill steps. Aluminium, platinum or palladium contacts 42 are formed by vapour deposition overall followed by pattern etching in a nitric-phosphoric acid mix. The diffusions are all effected through holes formed by conventional photolithographic techniques in thermal oxide layers. Arsenic is the dopant in regions 32, 34, boron in 37, 38 and phosphorus in the collector. The decline in current gain # with falling collector current is far less than in an otherwise identical device formed on a 111 orientated substrate. Manufacture of an oxide or nitride passivated planar epitaxial transistor (Fig. 1, not shown) with a phosphorus doped emitter and of an enhancement mode IGFET with N+ phosphorus doped source and drain regions is also described. The IGFET has a lower threshold voltage than its 111 orientated counterpart.

Patent ES-421419-A1 (ES)
Title: Synthetic natural gas production
IPC: C10J1/213
Filed: 1973-12-13
Abstract: A process for the production of synthetic natural gas or town gas is described wherein the hot gaseous product of the partial combustion of a carbonaceous fuel, containing hydrogen and carbon monoxide, is passed into a carburetting zone at a temperature of from 700 to 1100 DEG C and therein enriched with a volatile hydrocarbon carburant which on evaporation into the hot gaseous product of partial combustion is thermally cracked into methane and lighter unsaturated hydrocarbons. The carburetted gas product is then passed into a hydrogenation zone maintained at a temperature sufficient to further decompose any remaining hydrocarbon carburant and to hydrogenate the unsaturated hydrocarbons. In this process coke formation in the carburetting zone is substantially minimized by introducing the volatile hydrocarbon carburant into the carburetting zone in the form of a thin layer of liquid which is maintained at a temperature below that at which thermal cracking occurs during the time the carburant is not adsorbed by the hot gas stream.
